β¦ Synopsis
Hermetically sealed "C" sized Li/LiAlC14* 6SOJcarbon cells containing bromine or bromide as additives have been prepared and galvanostatically cycled at room temperature. The discharge and charging curves for these cells were compared with baseline cells. Cells containing 10% added bromine showed approximate 20% increase in initial cell discharge capacity, and their charging potentials were approximately 0.2 V lower than baseline cells. These performance improvements were observed even after extensive cell storage. Cells containing added bromide had poorer performance than did baseline cells.

Both Raman and 7Li NMR spectroscopic data of 0.2 M LiAICl, and LiGaCL in Iiquid sulfur dioxide indicate that ionic structuraI changes occur near 25 "C, thus supporting observations from conductivity and cyclic voltammetric studies.

Aromatic and aliphatic sulfones and, more particularly, dimethyl sulfone (DMS02), used as cosolvents with sulfur dioxide allow the dissolution of various lithium salts. The dependence of the conductivity on the concentration of both lithium salts and DMSOz has been studied. Lithium bromide and LiCl
